ATTORNEY PatentedfJune 18, v1935 UNITEDPST' Applicat `'norton oAR'roN This invention relates generally tol cartons or containersV and more particularly to an improved construction of cellular carton of the type adapt-- ed to receive eggs or other fragile rarticles re' quiring protection in the'handling thereof.

Among the principal objects of :the *present invention is to provide a cellular carton wherein the longitudinally and transverselywextendingdivision walls thereof are formed from ai' single 'blank and 'wherein meansl are provided for ef"-A fec'tively interlocking said divisionjwalls to af'- ford la'substanti'ally rigid' and self-sustaining structure; to provide a cellular carton wherein the longitudinal` and transverse walls are so'Y related; tofeach other that thevassemblythereof into the form of a complete carton-is effected expeditiously-by a simple manual Without necessitating the use of any special tools yor assemblingdevicesfto provide in a cellularA carton a separate,-'readily insertable means which functions not onlyi to interlock the longitudinal and transverse partition walls but which also serves to supportthe'bottommwall of the carton lagainst collapse; lthe said bottom f wall being suspended vfromfsaidreadily inserta-V ble means instead offfrom the transversepartition walls as hask heretofore been the general practice in cellularI cartons of' the type with which` this invention isy concerned; lto provide` an improved construction' offtoplid'or ,closure for thefcellular carton,jsaid lid Vor closurefbe-i ing so designed as to enable it jto be Lquick# detachably secured to the` carton; `and to generally improver the constructionA ofthe' carton so" that .whenjeggs or similar articles are "res'pec-f tivelyi received within the' 'cellular compartments thereof they are so supported' that the upper'4 portions thereof are sufli'cientl'y exposed'to'facilitatetheir easy removal from the carton.' 1 y Other objects of the invention will'be apparent morel fully hereinafter.

rIhe invention consists substantially inthe combinationQconstruction, location and relative ar- I rangement of parts, allas will appear rnoreffully.

Such a material, which will meet the re an endieivaticnai View oi thebogf i y the box', vaportion y cf the integral lid thereof being. cut away torexelevational view of the-box f quirements of the present invention,y is ineXpen-g ably'estamped to provide a series of partially cut out partition members 2l, each of these partition members being integrallyk anchored to kthe opposite sections l'iand 20by means of'triangular connecting strips or tongues 22.*k The free ends of each partition--member 2l "are vso cut along theline 23 to provide a'pair of laterally spaced substantially triangular projections V24-v 24,-at the same time that each 'partition mems ber is provided with an upwardlyy extending projection 25. These partition members`v 2l nare adapted to be swung into "planes substantially paralleling each other and extending' at' right angles to thefiat plane of theblank Ill.

In the carton constructed of the blank shown in Figure 1, the lid or top closure member therefor` is' formedas an integral part ofthe blank,` this lid being the section`l2r of the blank.v It

extending partition member, these notches 2'6"' being adapted to respectively receive the bottom'v edges of the transverse partition membersgl,

Each of the transverse `partition membersI 2l is providedvwith an openng. 211% therein,- lthese Y openings being so located in the severalmem'- bers 2I that when the latter are properly en-v gaged with the longitudinally extending parti-" tion' memberi the common". axis of the `aligned openings 27 is substantially: coincident with the ridgeof the longitudinally extending partition member. Y t

When the blank I is expanded into theshape of the box shown in Figuresn 2 and 3, it will' be observed thatthe sections I3 and I8 constitute the opposite side walls thereof, the sections I4 and II constitute the inwardly and downwardly inclined portions lof the bottom wall, and the sections I5 and I 63` constitute the upwardly inclined portions of the bottom-wall. The strip. is adapted to be glued or otherwise secured-tol theinner surface of the sidewall;I3-, while the section I2-ccnstitutes the lid of the carton, this section being adapted to rest upon the upper edges ,ofl the transverse partition members 2I. The end section II of the blank constitutes the securing lap which is adapted to be bent downwardly along,y the,k scored line a for connection with the side-v Wall- I8 in the mannerto be hereinafter described. Inuthis connection, it will'be observed that the outer .or free edge of the section` II is lprovided with a plurality of longitudinally spaced. tongues 28. Reverting again to 1 the blank shown in Figure 1, it will be observed that the transverse partition members 2| in that edge thereof which is coincident with the scoring line h are respectivelyprovided withcurved i 4incisions 29, it being noted that when the blank isexpanded-into the form ofthe completed box,

these incisions 29 provide spaces 30 ofA substantially semi-circular form between the side edgesv of thetransverse partitionv membersy and the outerwallel of the box, these semifcircular spaces being respectively located immediately beneath the triangular connecting strips 22.

In order to eilect desired. and necessary interf-A locking relation between transverse partition members 2I and the longitudinally extending partition member formed by the Vsections I5and I6, a separately insertable locking str-ipl 30 is employed, this strip being shown most clearly in1Figure 4 whereinit will be observed that it consists merely of a relatively narrow strip folded upon itself, the longitudinallyfextending edges 3l lof the strip being' preferably spaced from' one another. In cross-section this'y strip-` v isl thus of `substantiallyI V-shape. This strip is projected through. the aligned openings 211( of.

the transverse partition members with the ridge 3.2.1thereof nest'cdfwithin the ridge formed by the members. I5 and I 6, the free-edges 3l of the locking strip being respectively in engagement with the bottomedges yofthe openingrZeI in the transverse partition members 2I. The locking strip 30 thus serves not only to effect a positive interlock between the transverse partition members 2I and the longitudinal partition but also as a support from which the bottom sections I5 and I6 of the carton are suspended.

With reference to the securing flap II of the lid, it will be observed that the tongues 28 thereof are respectively provided with freely projecting portions 33` extending longitudinally of the carton and in such direction that said portions 33` thereof are adapted to be respectively projected into the spaces 33a formed between the side .edges of: the transverse partition members 2I and the sidewall I8 of the box. The tongues 28 are thusl frictionally engaged between side wall YI8 of vthe box and the proximate edges of the transverse partition members at the same time that they are prevented from being vertically disengaged from the box by the triangular supportinggstrips 22,. y

In Figures 5to- 8, inclusive, a modified form of the boxis illustrated, it being observed; however, that, in this modified. form of box the transverse partition. members are interlocked withy the longitudinally extending central partition member by means of a separatelyv insertable locking'strip, exactly as that employed in connection with the VAbox previously described.

The modied form of box differs from that pre- Viously described; inthe following respects; The blank 34 ofA which-it is-constructed does not include any lidfsection but instead includes-merely the sections 35 36, 3I,r 38,v 39, 4U, 4I: and 42l which respectively correspond to the sections I3 to20-of Figure 1t The lidsection of. the boxis formed'offa-separate blank 43 shown in Figure 6, this blank 43 beingprovidedwith scoring lines iandjc lwhich-divide the blanks into the sections 44; 45 and 46, theiintermediate sectionV 45 con.- stituting'- the lidproper and the opposed sections 44` and '46,c`onstituting, the securing flaps by whichthe lid is secured to the carton` proper.

Itwill be observed that thesesecuring naps 44 and 46 l. are respectively identical with` the securingnap II offFigure 1.both.in\structure and in operation.

The transverse partition members 41 of the blank 34' differ somewhat from the corresponding partition membersZI of the blank I0; In

the first place. it will be noted that the curved incisions48 areprovidedvin each side edge of the partition member,` Also, it will be observed that the opposite. side edges ofthe transverse partition members 4I are tapered inwardly along the lines, 49-49.' in. consequence of, which there is provided as integral parts `of the sections and 42, longitudinallyY spaced acute angle projections 5U.V |Ifliese relatively sharp-pointed projections 50 projectfupwardly in the plane of theopposite side walls of the carton when expanded into shape and above the upper edges thereof rto* such-extent that they serve as guidingy elements for the securing flaps of the lid 43 during the' operationhof securing the latter in Y position.v Inaddition, as appearsmost clearly infFigur'ef'?, these pointed'- projections f5ll, particularly when combined with the arcuately shaped portions 5I' are ideally adapted for ornamental purposes-:inasmuch as4 they represent theV head of:r a chick projecting upwardly from the upper edges of the side walls of the carton. 'I 'o increase-the effectiveness of4 this chickhead design, the upwardly extending projections 50 and 5I may be colored or otherwise configured vman ently lock the box lin expandedform.r s

assemble; one hand being, held below the box,`

whilethe other handis employed to position thejtransverse partition walls in vertically parallel lrelation whereby to` cause'the'bottom edges of. said transverse walls to be respectively seated within the notches or slots 26 provided in the ridge ofthe longitudinallyextending partition. When the sidewalls` of the, box are then compressed together, the natural result is to seat the. transverse partition wallsfurther` into the notches 26 so' as to present .the ridge` of the members l5 and l5 abovethe bottom edges of the aligned openings 21. Themember may then tbe slipped readily into vposition to per- In the form of boxshowninFigures inclusive, jthe lid may beremoved entirely by shifting the same longitudinallyy of the boxA to eieot the disengagement of all of the tongues Should it not be desired to remove the lid entirely, one

or the vother edges thereof Vmay be disengaged' from the carton while the oppositey edge remains engaged therewith, the lid "thus operating ex- .actly inthe manner of thelidof `the box shown in Figures 1 to,` inclusive. In other words, the lid may be swung upwardly. aboutv either ofthe scoring lines jor lo exactly in the manner of a hinged lid.

:i A A further and important advantage ofthe carton,constructedi as hereinbefore described and as showny in the accompanying drawing resides. in the fact that when thecarton is tobe shipped orstored and the conservation of space becomes an important factor, it may becompressed vinto substantially. ilat shape even thoughthe anchori ing strip (20, of Figure 1 andMk of Figure V 5) is glued or .otherwise permanently secured to one wall vof the carton, the compressing of thev carton being effec/ted along the scoring lines` c and g of the carton shown in Figure?,y and. along the scoring'lines l and m of the carton shown in Figure, 8. Gfr course, the compressing'may be effected along other score lines as desired, it

stances whereA the carton is tobe shipped or stored in compressed condition, the' transverse partition walls are disengaged from the longitudinallyvextending partition and lie in'a subiy stantially Aflat plane.

It will be understood, of course, that the invention is susceptible of various changes and modifications without departing from the real spirit or general principles thereof and it is accordingly intended to claim the same broadly, as well as speciiically, as indicated in the appended claims. i y
